Claims

[Claims for Utility Model Registration] A disk rotation mechanism that rotates the disk by having a rotating body that engages with the disk of a magnetic disk cartridge, and that records or reproduces a signal by contacting one surface of the disk. one magnetic head; another magnetic head disposed opposite to the one magnetic head so as to contact the other surface of the disk to record or reproduce signals; and a magnetic head that supports the one magnetic head. a head carriage that moves in the radial direction of the disk; a head support arm that is rotatably attached to the head carriage and supports the other magnetic head via a spring member; a spring for applying a biasing force to the head support arm in the direction of contacting the magnetic head; a mechanism for moving the head carriage in the radial direction of the disk; and a mechanism for moving the head carriage in the radial direction of the disk; a first position in which the disk is disengaged from the rotating body; and a second position in which the disk engages the rotating body; a cartridge holder configured to guide the cartridge from the first position to the second position; a cartridge holder moving mechanism for moving the cartridge holder so as to guide the cartridge from the first position to the second position; The other magnetic head is brought into contact with the other surface of the disk in response to the operation of the holder moving mechanism or the cartridge holder when the magnetic head moves from the first position to the second position. and a head load control mechanism for displacing a head support arm, which is insertable into the cartridge holder in the same manner as the cartridge, and which is inserted into the second position of the cartridge. and the second position of the cartridge.
The head load control mechanism is engaged with the head load control mechanism to prevent the other magnetic head from contacting the one magnetic head at the same position as the magnetic head, and is in a non-contact state with respect to the one and other magnetic heads. 1. A protective sheet for a magnetic disk drive device, characterized in that the protective sheet has a portion that is formed such that the magnetic disk drive is protected, and that restricts movement of the head carriage.
